PAPER-CUTTING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 228,686, dated June 8,1880. Application filed February 20, 1880.

To all whom it may concern:

Be it known that I, GRANGER W. SMITH, of Chili, in the county of Monroeand State of New York, have invented a new and useful Improvement inPaper-Cutting Machines, of which the following is a specification.

My invention relates to a machine for trimming the edges of magazines,pamphlets, or books, and for cutting paper into sheets of differentsizes, and for other similar purposes.

The invention consists in a novel construction, arrangement, andcombination of an adjustable table for holding the book or paper to betrimmed or cut, a frame for supporting said table, an adjustable bar forclamping the book or paper, and a knife used for the trimmin g orcutting process, all as hereinafter particularly described.

In the accompanying drawings, Figure 1 is a perspective view of anapparatus embodying my improvements. Fig. 2 is a section taken in theline a; a, Fig. 1. Fig. 3 is a detail sectional view. Fig. 4. is a viewof the knife.

Similar letters of reference indicate corresponding parts.

A represents a frame provided with ways a a. B represents a board, whichI call the table, resting on the frame A and sliding on the ways a a. Ois a board attached to one edge of the table B at a right angle with theupper surface thereof. D D are screws set in the frame A, and providedwith thumbnuts 6 c and washers f f. G is a bar resting on the frame A,above the table B, transversely to the line of travel of said table. Gis a bar attached to the bar G in such a manner as to leave a slot, 9,between the two parts. If desired the two parts G G may be all in onepiece. I prefer, however, to make the bar G of wood and the bar G ofmetal, with its lower edge beveled upward and outward.

H H are screws set in the frame A, and provided with thumb-nutsia'.These screws pass through holes in the bar G, and are surrounded byspiral springs S S, working in seatss s in said bar G and in the frameA.

The table B and an upright board, A on the frame A are marked with ascale representing inches and fractions thereof, in order to facilitatethe adjustment of the table, as hereinafter described.

block, L, provided with a thumb-screw, Z.,

This gage-block slides on the blade K, and is held at any desired pointthereon by tightening the thumb-screw.

In using this apparatus the book or paper to be trimmed or cut is laidupon the table B with the upper left-hand corner of the paper fitting inthe corner formed by the junction of the boards A and O. The table isthen adjusted to such a position as to bring the slot g exactly over theline where the cut is to be made. The table is then secured in positionon the frame by tightening the nuts 0 0, so that the washers ff will'bear firmly on both the frame and the table, and the book or paper issecured in position by tightening the nuts 2' i, so as to press the barG firmly down upon it. The gage-block L being adjusted to correspondwith the distance from the top of the slot g to the surface of the tableB, the blade K is inserted in the slot g, and the cutting is performedby grasping the handle K and drawing it toward the person.

The bar G touches the work only sufficiently to prevent the paper frombeing torn, and the beveled lower edge of the bar enables the cuttingsto be readily pushed outward away from the blade as the operationproceeds.

When the cutting or trimmingis completed the nuts 15 t are loosened,when the springs S S raise the bar G, so as to allow the work to beremoved.

Having thus described my invention, I claim as new and desire to secureby Letters Pateut In a paper-cutting machine, the combination of theblade K, having a diagonalchiseledge and handle, K the slotted slidinggage block having screw l, the slide-table B, havin g board 0, and theblock GG held by screws H and nuts i, as shown and described.
